"The first greenhouse built in 1866, probably by Professor Prentiss, stood where the bath house now stands and was torn down and the plants taken to the second building in 1874, located on a projection near the botanic garden. This second building was erected by Lord & Burnham and the third building now standing (1913) on the same site as the second one, was erected by the same company." [1]
